Does anyone have more details on this defensive publication process? I'm (on behalf of emdebian) an OIN member and didn't know/had forgotten. In principle timely defensive publication is a complete antidote to patents, but of course many of us don't do it, or don't do it in a way the patent office is likely to notice. So this seems like a really useful idea if it was just possible to get people to pass on every trivial idea they had today, and OIN could keep up writing them all up. You almost want something like a bug reporting system.
The problem it has is that, like the 'peer to patent' system, there is little incentive for developers to actually spend time on it. Actually the incentive is huge of course - defeating the whole shitty-patents nonsense that is the bane of everyone's lives, but it's so diffuse that very few of us (apoproximately none so far as I can tell) are actually spending time on peer to patent or filing 'please write this up' requests with OIN.
